Effective January 1, 2020 an amendment to the Construction Projects Regulation under the Occupational Health and Safety Act will clarify requirements for temporary stairs. The changes will:

• Clarify where temporary stairs should start and end (i.e. clearly requiring temporary stairs in underground levels).
• Exempt an additional specific situation where the installation of temporary stairs may not be possible (i.e. where formwork or falsework is erected to a suspended slab).

For more information, read the amending regulation, O.Reg. 327/19, which amends O. Reg. 213/91 – Construction Projects:
